IMPROVEMENT IN GRATES.

@ligt Sflgihnle Infant-iu in their rttrts ntmt mit making part uf tlgsame.

TO. ALL WHOMtI'l MAY CONCERN:

Be itknown that I, WILLIAM KEISER, of Stroudsburg, in the county ci'Monroe, and State of Pennsylvania, have invented a new and usefulImprovement in Groes; and I do hereby declare that the following is afull, clear, and exact description thereof, which will enable othersskilled in the art to make anduset ence being had to the accompanyingdrawings,l forming part of this specificatiom The object of thisinvention is to form a grate for stoves and ranges in suoli a mannerthat the coal on the grate may be effectually cleansed of ashes andother incouibust-ihle substances by shaking. The whole grate inay bedumped in one direction. And the invention consists in making the gratein two parts, and operating cach part from the outside ot" the stove inthe manner hereinafter described.

Figure 1 represents, a top or plan view of the grate, showing the framewhich sustains the fire-brick, the stationary part of the grate, and themovable part, which is'oolored in the drawing.

Figure 2 is a cross-section through the line x x of fig. I.

Similar letters of reference indicate like parts.4

A represents the frame, which supports the grate. This is, of course,proportioned to the size ofthe stove or range, and' is iliade ci'sufficient strength to sustain the loaded grate and fire-brick, whenbricks are used. B is the stationary part of the grate, or it isstationary when the other part is shaken, but in dumping the two partsmove together. a a represent pivots, which are attached to B, which restupon the frame A, and upon which one side 'of the grate is supported,and also upon which the grate turns when it is dumped. C is the otherpart of the grate. Its hars rest in recesses in the other portion, bywhich it is guided in the process of shaking. The stationary part B isdeeper than C, so that C rests in B with their upper surfaces on a level`with each other. D is awrench, by which the grate is raised afterdumping, as a portion of it fits on to the square end ofthe pivot at e.There is a hole on the end of the wrench which fits on to a pin, h, inC. It also has a circular slot, which sets over a pin, h', in thefra-me, so that a lateral movement ofthe wrench gives C a motionlengthwise. al represents straps, which 'are attached to B, and whichextend over the outside bars of C to keep C in place, as seen inthe'drawing. The grate is supported in a horizontal position by asliding-rod, f, which has ledges upon it, g, upon which that side of thegrate rests` When theV rod f is drawn out the grate drops.

What I cla-im as new, and desire to secure by Letters Patent, is

The arrangement and combination of the parts Band C with the frame A,substantially as described.

I claim the straps d and the wrench D with the pins rh, as and for thepurposes set forth.
